I use essentially this recipe with frozen rhubarb. It is a very easy recipe when using frozen rhubarb and has gotten rave reviews from all that have tried it. I did find I needed to bake it a wee bit longer. Delicious.
2 lbs rhubarb (I use frozen)
1 cup white sugar
1/4 cup flour + 1/2 cup flour
1/2 cup Earth Balance margarine
1/2 cup brown sugar
1 cup rolled oats
1/2 teaspoon cinnamon
-Preheat oven to 400°F.
-Mix together rhubarb, white sugar and first 1/4 cup flour. Place in a 13×9-inch baking dish.
-Cut together the remaining flour, EB, brown sugar, oats and cinnamon.
-Sprinkle over rhubarb.
-Bake 40-50 minutes.
